WINDOW-FRAME.

To all whom it may concern:

Be it known that I, IVARRENB. HARRIS, a citizen of the United States,residing at Millbury, in the county of \Vorcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement inVVindow-Frames, of which the following is a specification, accompaniedby drawings, forming a part of the same, in which Figure 1 represents aperspective view of a portion of a window frame embodying my invention.Fig. 2 is a transverse sectlonal view through the cover of the weightpocket on the plane of the broken line 2--2, Fig. 1. Fig. 3 is alongitudinal sectional view through the cover of the weight pocket onthe plane of the broken line 33, Fig. 1, and Fig. 4 is a perspectiveview of the cover of the weight pocket removed.

Similar reference characters refer to si1nilar parts in the difierentfigures.

My present invention relates to an improved construction of the cover ofthe weight pocket in a window frame, and it has for its objects toenable the cover to be formed of the same piece as the window frame, andto so construct the cover as to enable it to be securely retained inplace by the employment of a single screw or nail, and I accomplishthese objects by the construction and arrangement of parts ashereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings, 1 denotes the upright side of awindow frame and 2 the sill. WVithin the side 1 are. formed pockets forthe movement of the window weights, which are inserted therein throughan opening formed in the window frame in the usual and well knownmanner. This opening I close by a cover 3, which consists of the pieceremoved from the frame in the formation of the weight opening 4, therebyenabling the opening and the cover to be formed by the same operationand obviating the necessity of employing a separate piece for the cover.I also construct the cover with suitable supporting and interlockingsurfaces with the window frame so that, when the cover is placed inposition, a single screw is sufficient to retain it in place.

My improved cover, which is represented in perspective View in Fig. 4,is provided on its sides with longitudinal shoulders 5 and 6, adapted torest against similar shoul- Specification of Letters Patent. PwtvgntedFlay 17, 1910. Application filed August 9, 1909.

ders formed in the frame. The upper end of the cover is provided with ashoulder 7 which abuts against a similar opposing shoulder upon thewindow frame, and the lower end is likewise provided with shoulder 8arranged to abut against a similar shoulder on the window frame.

In the construction of my improved cover I out two saw kerfs 9 and 10 onthe back side of the board 11 which forms the upright side of the frame.I also form two saw kerfs 12 and 13 upon the outer side of the board 11.The distance between the saw kerfs 12 and 13 is sufficiently greaterthan the distance between the saw kerfs 9 and 10 to form the shoulders 5and 6 on the cover and corresponding shoulders 14 and 15 in the windowframe. The position of the saw kerfs 12 and 13 is indicated by thebroken line 16, and the position of the saw kerfs 9 and 10 is indicatedby the broken line 17, Fig. 3, the saw kerfs upon opposite sides of theboard 11 extending approximately half way through the board. Transversesaw kerfs 18 and 19 are then formed on the back side of the board 11between the saw kerfs 9 and 10, and similar transverse saw kerfs 20 and21 are formed on the front side of the board between the saw kerfs 12and 13. The saw kerf 18 is formed at some distance above the saw kerf20, so as to provide the abut-ting surfaces between the board 11 and thecover 3 on the plane of the broken line 22, and the saw kerf 21 isformed some distance below the saw kerf 19 in order to form the abuttingsurfaces between the board 11 and cover 3 on the plane of the brokenline 23, Fig. 3.

When the saw kerfs are formed as above described, a blow from a hammer,applied to the back side of the cover in the plane of and in thedirection of the arrow 24, will separate the cover from the board 11,splitting the fibers of wood where the cover is attached to the board 11between the saw kerfs. The cover when removed presents the appearanceshown in perspective view in Fig. 4, having shoulders 5 and 6 which abutsimilar shoulders 14 and 15 in the board 11 and form a support for thecover, when placed in position, throughout its length.

The separation of the cover from the board 11 between the saw kerfs 18and 20 and the saw kerfs 19 and 21 form the shoulders 7 and 8 on thecover, which fit corresponding shoulders in the board 11 when the coveris placed in position. The engagement of the shoulder 7 with the board11, when the cover is placed in position, holds the upper end of thecover from falling outwardly. The shoulder 8 and the longitudinalshoulders 5 and 6, abutting opposing shoulders on the board 11, hold thecover from being pressed inwardly. A screw 25 is then inserted in thesaw kerf 21 to hold the lower end of the cover from moving outwardly.

I claim,

1. A window frame having an opening for the admission of sash weights, aremovable closin strip, longitudinal shoulders on the sides of saidclosing strip, corresponding opposing shoulders on said window framelengthwise said sash weight openin a transverse shoulder on one end ofsaid closing strip facing toward the inside of the window frame, atransverse shoulder on the opposite end of said closing strip facingaway from the inside of the window frame and corresponding opposingshoulders on the window frame at the ends of the sash weight opening.

2. A window frame having a sash weight opening, a cover for said openinghaving shoulders at its sides and one end facing away from the inside ofthe window frame, a shoulder at the opposite end of said cover facingtoward the inside of the window frame, said shoulders lying insubstantially the same plane, and corresponding opposing shoulders onthe window frame.

3. A window frame having a sash weight opening, a cover for said openingformed from the side of the window frame by longitudinal saw kerfs, indifferent planes, by which longitudinal shoulders are formed at thesides of the cover and by transverse saw kerfs at the ends of the coverin different planes, whereby transverse shoulders are formed at the endsof the cover, one of said end shoulders facing in the same direction asthe longitudinal shoulders and the other end shoulder facing in theopposite direction.

A. A window frame having a sash weightopening and a cover thereforprovided at its sides with shoulders 5 and (3 and at its ends withshoulders 7 and 8, said end shoulders facing in opposite directions, andcorre sponding opposing shoulders at the ends and sides of the sashweight opening.

5. In a window frame having a sash weight opening, a cover for saidopening provided at its sides with longitudinal shoulders engagingcorresponding longitudinal shoulders at the sides of the sash weightopening and forming seats for said cover, a shoulder at one end of saidcover transversely thereto engaging a corresponding shoulder at one endof the sash weight opening and holding said longitudinal shoulders incontact.
